Thorna's Planor SR employs LED technology to guarantee lighting quality in school or office environment.
The lay-in luminaire uses a dimmable Cree 58W LED module with active colour management and a micro prismatic lighting technique that regulates the light through pyramidal prisms. This ensures colour temperature stability of 3500K through life, a colour rendering index (CRI) of 92 and reduced glare.
